Those ugly, dark streaks on an asphalt shingle roof are
not a defect in the shingles or a sign of a bad
shingling job. It's algae that causes the roof to look
bad. Some experts say algae may cause shingles to
deteriorate prematurely.

This type of hardy, blue-green algae (Gloeacapsa magma)
thrives in warm, humid climates. In the Midwest, it
normally appears on a north slope where shade and
moisture support its growth.. However, the problem is
most severe in the southeast Gulf states, where entire
roofs can be covered in as little as four years.

The algae feed on inorganic filler materials such as
calcium carbonate in asphalt shingles.

What is the Solution?

1. Well,
you could ignore the problem. But if you do, the
moss, mold and algae will eventually destroy your roof.

2. You
could get a new roof if you would like to spend between
$4,000 and $10,000+.

3. Or you
could take charge and put an end to the problem. Fungus
should first be removed by washing with a non-hazardous
chemical treatment.

Did You Know?

1.
Moss can break down fibers in shingles, forcing them apart
and allowing leaks.

2. Fungus reduces the ability of the roof to reflect
away light and heat, making for higher air conditioning
bills.

3. A roof covered in fungus detracts from the
appearance of the whole house, since the roof is one of
the largest visible surfaces

4. Many roofs are replaced prematurely due to damage
by neglected moss
